FWIW every country requires you leave and come back to change or renew visa status. The computers and processes are all setup at points of entry and just aren’t designed for people that don’t physically leave/enter.

It’s so common the guys at the us/Canada land border call it “flagpoleing” because you literally drive a u turn around the flagpole and go back. I’ve done it a dozen times, even driving 4 hours each way in a gnarley winter storm into Alaska and back to Canada at -45.
